安定器にて安定させるジアゾ複写機において、前
記安定器を前記蛍光灯の光量を可変できる高周波
点灯装置により構成し、この安定器を制御して前
記蛍光灯の光量を非露光時に最大光量の１／２以
下に減光させる安定器制御回路を設けたことを特
徴とする光量制御回路。 In a diazo copying machine that performs exposure using a fluorescent lamp and stabilizes the current of the fluorescent lamp with a ballast, the ballast is constituted by a high-frequency lighting device that can vary the amount of light of the fluorescent lamp, and the ballast is controlled. A light amount control circuit comprising a ballast control circuit that reduces the light amount of the fluorescent lamp to 1/2 or less of the maximum light amount during non-exposure.
